Here is a cool vintage long sleeve shirt. It's a 50/50 poly and cotton blend. White background with striping of red, gray, blue, and yellow. Five button front, a button on each cuff, and a pocket on the left breast. Super thin and light weight, sheer, very soft and comfy, and in amazing shape! The tag says 15 - 15 1/2, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 21"

Shoulder to end of sleeve (including cuff) 24"

Length 27"

This item is sold from a vintage boutique in Roanoke, VA.
